I don’t even know if we can have a fileobserver running in background with LL, but I’m trying..

Well after re-reading the docs, FileObserver is an abstract class, so I need to create a class that extends from FileObserver.. How can I do this in JS ?

You need something called Java Adapter
I never used it, but it is something like
new JavaAdapter(FileObserver(pathToWatch),{ …} );

TrianguloY how do you know this?

Because Lukas Morawietz found it, but that function was obfuscated, and asked Pierre Hébert to not obfuscate it.
And I read the post 🙂

Maybe it has something to do with the Java2JS engine.. Do you know his name?

1. Yes, Java adapter would be the right thing to use, but
2. Java adapter doesn’t work on Android, because it needs Java bytecode.
3. I asked the developers of Rhino and they said: it would theoretically be possible to adjust this for android, but it’s a lot of work and it’s not planned.
4. The only way to extend a class is to ship it in an apk and then load it in the script.
